Abstract (en)
[origin: WO2020069209A1] Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive, from a gNB, configuration information related to a 2-step random access (RA) procedure between the UE and the gNB in unlicensed spectrum. The 2-step RA procedure may include: an uplink MsgA message that includes, within a random access occasion (RO), a MsgA preamble and a MsgA payload; and a downlink MsgB message that includes, within another RO, a MsgB PDCCH and a MsgB payload. The configuration information may indicate: resources allocated for the MsgA preamble; and a mapping between the resources allocated for the MsgA preamble and the MsgA payload. The UE may determine the resources allocated for the MsgA payload based on the resources allocated for the MsgA preamble and the mapping.
